2.4 Intel® 82571EB Gb Ethernet Controller
The Intel® 82571EB Gb Ethernet Controller is a single, compact component with two fully
integrated Gb Ethernet Media Access Control (MAC) and physical layer (PHY) ports. This
device uses the PCI Express* architecture (Rev. 1.0a) and also enables a dual-port Gb Ethernet
implementation. The Intel® 82571EB Gb Ethernet Controller provides two IEEE 802.3 Ethernet
interfaces for 1000BASE-T, 100BASE-TX, and 10BASE-T applications. Both ports also
integrate a Serializer-Deserializer (SerDes) to support 1000BASE-SX or 1000BASE-LX (optical
fiber) and Gb backplane applications. In addition to managing MAC and PHY Ethernet layer
functions, the controller manages PCI Express* packet traffic across its transaction, link, and
physical/logical layers.
The Intel® 82571EB Gb Ethernet Controller for PCI Express* is designed for high-performance
and low memory latency. The device is optimized to connect to a system Memory Control Hub
(MCH) using up to four PCI Express* lanes. Wide internal data paths eliminate performance
bottlenecks by efficiently handling large address and data words. Combining parallel and
pipelined logic architecture optimized for Gb Ethernet and for independent transmit and receive
queues, the controller efficiently handles packets with minimum latency. The controller includes
advanced interrupt-handling features and uses efficient ring-buffer descriptor data structures
with up to 64 packet descriptors cached on chip. A large 48 Kbyte per port on-chip packet buffer
maintains superior performance. Using hardware acceleration, the controller offloads tasks from

the host, such as checksum calculations for Transmission Control Protocol (TCP), User
Datagram Protocol (UDP), and Internet Protocol (IP); header and data splitting; and TCP
segmentation.
2.5 EEPROM
The Dual Gb Ethernet I/O module provides a SPI serial EEPROM to store configuration and
informational data. This includes pre-boot configuration data, MAC addresses, and serial
numbers for the 82571EB.
2.6 PCI Express* p16-x4 Connector
The Dual Gb Ethernet I/O module contains one 50-pin connector.
2.7 Ethernet Magjack
The Dual Gb Ethernet I/O module contains two Ethernet Magjacks which are compatible with
10/100/1000 Mbps Ethernet connection.
External 4 Port SAS I/O Module (AXXSASIOMOD) Intel ® I/O Expansion Modules
3. External 4 Port SAS I/O Module (AXXSASIOMOD)

3.4 LSI* SAS1064E 3.0 Gbit/s Serial Attached SCSI Controller
Integrated on the SAS I/O module is an LSI* SAS1064E Serial Attached SCSI (SAS) controller.
The LSISAS1064E is a four-port, 3.0 Gbit/s SAS/SATA controller compliant with the Fusion-
MPT* architecture, and provides a four-lane PCI Express* interface. The point-to-point
interconnect feature of the PCI Express* bus limits the electrical load on links, allowing
increased transmission and reception frequencies. PCI Express* transmission and reception
data rates for each full-duplex interconnect is 2.5 Gbit/s.

Figure 9. LSI* SAS1064E Block Diagram
PCI Express* implements a switch-based technology to interconnect a large number of devices.
Communication over the serial interconnect is accomplished using packet-based
communication protocol. Quality of Service (QOS) features provide differentiated transmission
performance for different applications. Hot plug/hot swap support enables “always-on” systems.
Enhanced error handling features, such as end-to-end CRC (ECRC) and Advanced Error
Reporting, make PCI Express suitable for robust, high-end server applications. Hot plug, power
management, error handling, and interrupt signaling are accomplished using packet-based
messaging rather than sideband signals.
Each of the four SAS PHYs on the LSISAS1064E is capable of SAS/SATA link rates of 3.0
Gbit/s and 1.5 Gbit/s. The user can configure ports as wide or narrow. Narrow ports have one
PHY per port. Wide ports have two, three, or four PHYs per port. Each port supports the SSP,
SMP, STP, and SATA protocols.
The SAS interface uses the proven SCSI command set to ensure reliable data transfers, while
providing the connectivity and flexibility of point-to-point serial data transfers. The SAS interface
provides improved performance, simplified cabling, smaller connectors, lower pin count, and
lower power requirements when compared to parallel SCSI. SAS controllers leverage an
electrical and physical connection interface that is compatible with Serial ATA technology.
The LSISAS1064E uses the Fusion-MPT* (Message Passing Technology) architecture, which
features a performance-based message passing protocol that offloads the host CPU by
completely managing all I/Os and minimizes system bus overhead by coalescing interrupts. The
proven Fusion-MPT* architecture requires only thin, easy-to-develop device drivers independent
of the I/O bus. LSI* Logic provides these device drivers.

Intel® I/O Expansion Modules InfiniBand* (SDR) Module (AXXIBIOMOD)
4. InfiniBand* (SDR) Module (AXXIBIOMOD)
The 4X SDR InfiniBand* I/O module is based on the Mellanox InfiniHost* MT25204 device with
the integrated Physical Layer SerDes. This card has a single 4X InfiniBand* copper port for
connecting InfiniBand* traffic at up to 10Gbps. This section provides a high-level description of
the implementation of this I/O module. This module is expected to end-of-life with the
S5000PAL/S5400SF server boards, not available for extended life support
